However, suitability depends on the environmentâs aggressiveness (chlorides, acids, humidity, temperature) and expected lifetime; for highly aggressive or long-term marine/chemical exposures, stainless steel or additional protection may be recommended. Verify coating specification and compatibility with your media and consult Eaton/DIN 2353 guidance for the exact application.
